1 claim. (critter-tmf This invention relates to asurgeons 4soapdispenser andis designedas'an improvement over the construction shown in`applicants copending appl-itionlserial No. 51f0057, now Pate' No.253,8"7;359,l The principal l Listo providea-highly efcient `cie'vioe ofthis harof Ithe us'r without it A"being necessary" for [the hands `orany Vother portion Yof the users body oniingincontact with the deviceorany part yA-neither object V`of theinv'ention is to {sojconstruct the'device so that Aall of the exposed `parts will be smooth and rounded sothat there will be no corners, pockets, or obstacles in which dirt orgerms may collect.

A further object is to provide an electronicallyoperated soap dispenserin which all operating parts will be completely protected and yet willbe readily accessible for replacement and repairs, and in which the soapcontainer can be quickly and easily replaced or removed withoutdisturbing the operating mechanism of the device.

Other objects and advantages reside in the detail construction of theinvention, which is designed for simplicity, economy, and eiciency.These will become more apparent from the following description.

In the following detailed description of the invention, reference is hadto the accompanying drawing which forms a part hereof. Like numeralsrefer to like parts in all views `of the drawing and throughout thedescription.

In the drawing:

Fig. 1 is a perspective View of the improved soap dispenser as it wouldappear in use.

Fig. 2 is enlarged longitudinal section therethrough.

Fig. 3 is a cross-section taken on the line 3-3, Fig. 2.

The improved dispenser is mounted on a backboard I0, and is completelyenclosed within a water-proof cover Il. The cover is formed with an openback for receiving the backboard Il] and with an open bottom and issecured to the backboard IIJ by means of suitable angle clips I 2. Thecentral portion of the housing is depressed as shown at I3 to form twoside shoulders I4, between which is a depressed portion I3 provided witha perforated drain I5.

A soap pan I6 is positioned below the depressed portion I3 and issupported on two angle corner clips I'I secured to the backboard ID andextending beneath the two rear corners of the pan I6. The rear wall ofthe pan I6 is held against the ohjectfof the in en ion l i n lego; .A,r' les-imp in, pan IBupori a bracket arm 20. The braci garan.tQfthabaCkPOM-- mit Iubo me ns .of,.sx, szr, .t B faut 9, .a 3f. 3,# ,e.w are pump cyli r is through la suitable check valve 23. The tube 22extends upwardly through the housing II, thence forwardly and downwardlyto a position over the perforated drain I5.

A pump lpiston 24 is reciprocally mounted within the cylinder I9. Thepiston 24 is preferably of the cup-washer type-that is, when .it movesdownwardly it spreads, to force soap into the tube 22, and when it movesupwardly it allows soap from the pan I6 to flow past the piston into thecylinder I 9.

The piston 24 is reciprocated from a piston rod 25 which is suspendedfrom one extremity of a rocking lever 26. The rocking lever 26 ispivoted intermediate its extremities, as shown at 21, from suitableyears on the bracket arm 20. The remaining extremity of the lever 26 isconnected to an armature 2l of an electric so-lenoid 28 secured to thebackboard I0. A tension spring 29 is stretched between the extremity ofthe lever 26 and a spring arm 30, secured to one of the clips I'I, so asto constantly urge the piston 24 upwardly in the cylinder I9. The pistonis forced downwardly by the action of the solenoid 28 in attracting thearmature 2'I.

The current supply to the solenoid is controlled by a photo-electricrelay set 3| of any of the standard commercial types. Such a setcontains a window which admits light to a photo-electric cell which isresponsive to light changes. The set also contains suitable amplifyingapparatus and a relay controlled thereby which in turn controis thecurrent supply to the solenoid 28 through suitable conductors 32. Thedetail construction of the photo-electric set is not illustrated, sincethese are standard pieces of apparatus which may be purchased on theopen market.

The set 3| is supported upon a suitable bracket from the backboard Il)in one of the side shoulders I4 so that its light-receiving window will`be positioned behind a transparent window 34 sealed in the housing II. Alight-emitting opening covered by a suitable lens 35 is alsoy positionedin the inner wall of the opposite side shoulder I4 so that the window34, the lens 35, and the discharge from the spout of the tube 22 will bein alignment with each other over the perforated drain I5.

An electric light source 36 is mounted in a receiving socket 31 on thebackboard I0 with its filament in alignment with the opening 35 and thewindow 34. .This causes a, beam of light to be transmitted through thelens 35 into the window 34 to energize the photo-electric cell in thephoto-electric set 3|, causing the relay therein.

This actuates the-pump piston 24 todischarge a predetermined quantity of soap yfrom the-cylinder I9Vthrough the spout 22 onto the hands of the user.
